Multiple Choice

A one-to-one function is given. Write an expression for the inverse function.
- $$f ( x ) = 4 x ^ { 3 } - 9$$

A) $f ^ { - 1 } ( x ) = \frac { x - 9 } { 4 }$
B) $f ^ { - 1 } ( x ) = \left( \frac { x + 9 } { 4 } \right) ^ { 3 }$
C) $f ^ { - 1 } ( x ) = \frac { x + 9 } { 4 }$
D) $f ^ { - 1 } ( x ) = \sqrt [ 3 ] { \frac { x + 9 } { 4 } }$
